摘要：
The asymmetric unit of the crystal consists of one sulfate ion, one water molecule and two 2,4-diamino-pyrimidine (DAP) molecules slacked parallel to the b direction with average perpendicular separations of 3.310(4) and 3.343(4)Angstrom, respectively. The tilt angle between the least-squares planes of the. two DAP molecules in the asymmetric unit is 2.1(1)degrees. The structure is stabilized by stacking forces, N-H ... N hydrogen bonds and N-H ... O hydrogen bonds.
